Analysis of a Mathematical Model of the Interaction between PIP3, AKT, and FOXO3a in Acute Myeloid Leukemia
... Abstract—The model of interaction between PIP3, AKT, and FOXO3a in the PI3K/AKT signaling pathways in Acute Myeloid Leukemia (AML) is described and analyzed in this paper. We assume that the biochemical reaction ...
